As you guess, yes, the need for electric energy is never ending. We use electric in just about every facet of our lives, from when we flip on the lights to walk into a room, to when we power an entire data center holding critical information for a nation or company.
In 2008, the world total of electricity production and consumption was 20,279 TWh (terawatt-hours). This number corresponds to an average consumption rate of around 2.3 terawatts continuously during the year. That demand continues to grow exponentially.
Along with the growth in demand for electric power, sustainable development, environmental issues, and power quality and reliability have become concerns.
Electric utilities are becoming more and more stressed since existing transmission and distribution systems are facing their operating constraints with growing load. Under such circumstances, distributed generation with alternative sources are an urgent task.
As the demand and need for electrical energy expands throughout the world, many countries are looking towards renewable energy sources, such as photovoltaic devices and wind electric generators.
